Fungal nail infections are one of the most common foot problems seen by podiatrists. Medically known as onychomycosis, this condition can cause nails to become thickened, yellow, brittle and difficult to manage. Many people find fungal nail infections embarrassing, while others experience discomfort when wearing shoes or walking.
Although fungal nail infections are rarely dangerous, they can be persistent and difficult to eliminate without professional treatment. Traditional treatments include topical antifungal products and prescription medications, but advances in podiatry have introduced another option: ND:YAG laser therapy.
In this guide, we explain how fungal nail infections develop, the available treatment options, and how laser nail rejuvenation may help improve the appearance and health of affected nails.

What Is Onychomycosis?
Onychomycosis is the medical term for a fungal infection affecting the nail. It most commonly affects toenails but can also occur in fingernails.
The infection develops when fungi enter the nail through tiny cracks or separations between the nail and nail bed. Once established, the fungus thrives in the warm, dark and moist environment inside footwear. Over time, the infection can spread deeper into the nail structure.
Common Signs of Fungal Nail Infection
Symptoms may include:
- Yellow, white or brown nail discolouration
- Thickened nails
- Brittle or crumbly nails
- Distorted nail shape
- Nails lifting away from the nail bed
- Debris building beneath the nail
- Difficulty cutting the nail
- Mild discomfort or pressure when wearing shoes
As the infection progresses, the nail may become increasingly thick and damaged.
What Causes Fungal Nail Infections?
Fungal nail infections are typically caused by dermatophyte fungi, although yeasts and moulds can also be responsible. These organisms thrive in damp environments and are commonly picked up in:
- Swimming pools
- Gym changing rooms
- Public showers
- Shared footwear
- Moist footwear environments
People are more likely to develop fungal nail infections if they:
- Have athlete’s foot
- Wear tight-fitting shoes
- Have diabetes
- Experience poor circulation
- Are over the age of 60
- Have damaged toenails
- Sweat heavily
- Regularly use communal changing facilities
These risk factors make it easier for fungal organisms to invade and persist within the nail.
Diagnosing a Fungal Nail Infection
Not every thickened or discoloured nail is caused by fungus. Trauma, psoriasis and other nail conditions can produce similar symptoms.
A podiatrist will assess the nail’s appearance and may recommend laboratory testing to confirm the diagnosis before starting treatment. Accurate diagnosis is important because treatment recommendations vary depending on the underlying cause. Paul Miller is a professional podiatrist based in Kent, he’s been part of the local communities since the 1990s and as one of the few HCPC State Registered practices in both Medway and Sidcup, we offer a comprehensive range of services, including Nail Surgery, Diabetic Foot Care, and Biomechanics.
Treatment Options for Fungal Nails
Topical Treatments
Antifungal lacquers, creams and solutions are often recommended for mild fungal nail infections.
While convenient, these treatments can struggle to penetrate thickened nails and often require many months of consistent use.
Oral Antifungal Medication
Prescription antifungal tablets may be suitable for some patients.
These medications can be effective but may not be appropriate for everyone due to potential side effects, medication interactions and medical history considerations.
ND:YAG Laser Therapy for Onychomycosis
ND:YAG laser therapy has become an increasingly popular treatment option for fungal nail infections.
The laser delivers energy through the nail plate and into the nail bed where fungal organisms reside. The goal is to create conditions that inhibit fungal growth while leaving surrounding tissue largely unaffected. Research suggests the 1064nm ND:YAG wavelength can penetrate deeply into the nail structure, making it particularly suitable for treating onychomycosis.
Nd:YAG laser therapy is a non-invasive procedure with no requirement for anaesthesia and minimal associated discomfort. It provides an alternative to long-term oral antifungal medication and avoids the potential systemic side effects associated with pharmacological therapy.
Laser fungal nail rejuvenation is a modern, non-invasive solution designed to target the infection at its source and support the growth of clearer, healthier-looking nails.
Treatment sessions are performed in a controlled clinical setting and typically require no recovery time. Clinical improvement is observed progressively as the affected nail grows out.
What Is Laser Nail Rejuvenation?
Laser nail rejuvenation refers to the process of improving the appearance and health of fungal nails using laser technology.
The treatment aims to reduce fungal activity, allowing healthier nail growth over time. As the infected nail gradually grows out, it may be replaced by clearer, healthier-looking nail tissue.
Because toenails grow slowly, visible improvement often develops gradually over several months following treatment.
What Happens During ND:YAG Laser Treatment?
Treatment is typically straightforward and requires no anaesthetic.
During the procedure:
- The affected nail is assessed and prepared.
- The laser is applied to the infected nail.
- Energy passes through the nail plate to target fungal organisms beneath.
- The session usually takes between 15 and 30 minutes depending on the number of nails treated.
Most patients experience only mild warmth during treatment. Multiple sessions may be recommended depending on the severity of the infection.
How Many Treatments Are Usually Needed?
The number of treatments varies depending on:
- Severity of infection
- Number of nails involved
- Nail thickness
- Overall health
- Compliance with aftercare recommendations
Many treatment protocols involve multiple sessions spaced several weeks apart.
Benefits of Laser Treatment for Fungal Nails
Potential benefits include:
- Non-invasive treatment
- No recovery downtime
- Minimal discomfort
- Suitable for many patients who cannot take oral medications
- Targets fungus beneath the nail
- Can be combined with other treatment approaches
Research suggests that combining laser treatment with appropriate antifungal management may improve overall outcomes in some cases.
How Long Does It Take to See Results?
Toenails grow slowly, typically requiring 9 to 12 months to fully replace damaged nail tissue.
Even when fungal organisms have been successfully reduced, the damaged portion of the nail must gradually grow out before healthier nail appearance becomes visible.
Patience and ongoing foot care are important throughout the recovery process.
Preventing Fungal Nail Infections Returning
After treatment, it is important to reduce the risk of reinfection.
Helpful steps include:
- Keeping feet clean and dry
- Changing socks daily
- Wearing breathable footwear
- Treating athlete’s foot promptly
- Avoiding barefoot walking in communal areas
- Disinfecting nail clippers and footwear regularly
Good foot hygiene significantly reduces the risk of fungal recurrence.
When Should You See a Podiatrist?
You should seek professional advice if you notice:
- Persistent nail discolouration
- Thickened nails
- Crumbling nail edges
- Pain when walking
- Recurrent fungal infections
- Difficulty cutting your nails
Early treatment is often easier and may help prevent the infection from spreading to additional nails.
Laser Nail Rejuvenation Prices
Our laser nail rejuvenation treatment uses advanced laser therapy to help improve the appearance of fungal nail infections. Treatment plans are tailored to the number of nails affected and typically involve a series of sessions to maximise results.
Initial Consultation
£50
During your consultation, your podiatrist will assess your nails, discuss your symptoms, confirm whether fungal nail infection is the likely cause, and determine whether laser treatment is suitable for you.
Treatment Prices
One Foot
£300
Includes up to 4 laser treatment sessions, spaced approximately 2–4 weeks apart.
Two Feet
£500

When Will I See Results?
It’s important to understand that fungal nail treatment is not an instant solution. Toenails grow very slowly and can take 12 months or longer to fully grow out.
As the treated nail gradually grows, healthier nail tissue should begin to replace the damaged portion. Improvements are typically seen over time as the nail naturally grows out following treatment.
